    Habit
    Spiny suffrutex 10–30 cm tall, 1 to several erect branches from a woody base; stems with fine white retrorse hairs mainly arranged in two opposite-decussate rows.
    Leaves
    Leaves linear or narrowly oblong, 3–6 × 0.5–1 cm, base cuneate, apex acute, mucronate, surfaces yellowish-hispid particularly on veins beneath and margin, hairs along margin with a ± bulbous base, with few to numerous fine white retrorse hairs when young; lateral veins 3–4 pairs; petiole 0–3 mm.
    Inflorescences
    Inflorescence axillary, single-flowered, sessile; bracteoles spinose, green with paler margin, 12–21 × 1–1.5 mm, margin entire or with 1–3 lateral teeth; pairs persisting at lower nodes as paired axillary spines, then whitish.
    Calyx
    Calyx green with paler margin, later scarious; anterior lobe ovate-elliptic or lanceolate, 12–18 × 3.5–5 mm, margin with 6–9 stiff spines 1–3 mm long ending in a bristle, apex spinose or bifidly so, surface with sparse to numerous fine crisped or straight white hairs particularly along margin, with sparse stiff yellowish hairs along main veins; posterior lobe as anterior but 15–21 mm long, apex long-spinose; lateral lobes linear-lanceolate, 6.5–9 mm long.
    Corolla
    Corolla 19–24 mm long, blue (according to Lindau), sparsely pubescent externally; tube 12–14.5 mm long, throat campanulate; limb subregular; abaxial lobe 6.5–8.5 × 5.5 mm; lateral lobes 7–10 × 4.5–5 mm; adaxial lobes as lateral pair but 3.5–4 mm wide.
    Stamens
    Stamens attached c.5 mm from base of corolla tube; filaments c.10 mm long; anthers c.1.7 mm long; lateral staminodes 1.3–1.7 mm long, pubescent, antherodes 0.7 mm long.
    Ovary
    Ovary with apical ring of minute crisped hairs; style glabrous; stigma subcapitate, 0.3–0.4 mm long.
    Fruits
    Capsule c.13 mm long, glabrous.
    Seeds
    Seeds c.4.5 × 4 mm.
    Distribution
    Also in Swaziland and South Africa (Mpumalanga).
    Ecology
    Open grassy shrubland with sparse Acacia trees on compacted, rugged ground; c.300 m.
    Conservation
    Conservation notes: Very rare, known from only three localities; recently (2012) confirmed to occur in Swaziland. Habitat data suggests it is tolerant of some disturbance; possibly threatened.
